Javascript:从2个数组中查找不匹配的对象

function findMismatchedObjects(arr1, arr2) {
  let mismatchedObjects = [];
  for (let i = 0; i < arr1.length; i++) {
    let found = false;
    for (let j = 0; j < arr2.length; j++) {
      if (isEqual(arr1[i], arr2[j])) {
        found = true;
        break;
      }
    }
    if (!found) {
      mismatchedObjects.push(arr1[i]);
    }
  }
  return mismatchedObjects;
}

function isEqual(obj1, obj2) {
  // 自定义判断两个对象是否相等的逻辑
  // 可以根据对象的属性进行比较，例如 obj1.id === obj2.id
  // 如果对象较复杂，可以使用深度比较的方法，例如 JSON.stringify(obj1) === JSON.stringify(obj2)
  // 这里只是示例，具体实现根据实际情况进行调整
  return obj1.id === obj2.id;
}

// 示例用法
let array1 = [{id: 1, name: 'John'}, {id: 2, name: 'Jane'}, {id: 3, name: 'Bob'}];
let array2 = [{id: 1, name: 'John'}, {id: 2, name: 'Jane'}, {id: 4, name: 'Alice'}];

let mismatchedObjects = findMismatchedObjects(array1, array2);
console.log(mismatchedObjects);

function findMismatchedObjects(arr1, arr2) {
  let mismatchedObjects = arr1.filter(obj1 => {
    return arr2.findIndex(obj2 => isEqual(obj1, obj2)) === -1;
  });
  return mismatchedObjects;
}

function isEqual(obj1, obj2) {
  // 自定义判断两个对象是否相等的逻辑
  // 可以根据对象的属性进行比较，例如 obj1.id === obj2.id
  // 如果对象较复杂，可以使用深度比较的方法，例如 JSON.stringify(obj1) === JSON.stringify(obj2)
  // 这里只是示例，具体实现根据实际情况进行调整
  return obj1.id === obj2.id;
}

// 示例用法
let array1 = [{id: 1, name: 'John'}, {id: 2, name: 'Jane'}, {id: 3, name: 'Bob'}];
let array2 = [{id: 1, name: 'John'}, {id: 2, name: 'Jane'}, {id: 4, name: 'Alice'}];

let mismatchedObjects = findMismatchedObjects(array1, array2);
console.log(mismatchedObjects);
